The divisity of galaxies. The galaxies are the giant (to hundred of billions of stars) star systems, where the stars are connected by gravitation laws with each other. ... Ther galaxy NGC 3031 . ... Each spiral galaxy has a core a flat disk where the spiral brancher locate. The stars and interstellar substance of spiral galaxies rotate around the core. ... In normal galaxies, such as our Galaxy, the great brightness of the core is accounted for the high concentration of stars. ...

... The vertical and slanted dashed lines in the first panel mark the separation distinguishing are as occupied by thick-disk objects according to Hanson et al. (1998) and Martin, Morrison (1998) , respectively. An abrupt change in the dispersion near V res 290 km/s (the vertical dashed lines) is apparent in all panels except the first. discussion in the text | next figure | privious figure . ...
